Abstract (en)

[origin: EP2832964A1] There is disclosed a heating method of honeycomb structure in which it is possible to suitably heat the honeycomb structure with less temperature unevenness during the heating and with less power consumption. The heating method of honeycomb structure includes a heating step of supplying a power to a honeycomb structure body 4 of a honeycomb structure 100 including the tubular honeycomb structure body 4 having porous partition walls 1 to define and form a plurality of cells 2 and a circumferential wall 3 positioned at an outermost circumference, and heating by electricity conduction, and a catalyst 7 loaded onto the partition walls 1 of the honeycomb structure body 4, to heat the honeycomb structure body 4 up to a target temperature, and in the heating step, there is provided, at least once, a supply power decrease section where the supply of the power to the honeycomb structure body 4 is stopped or the power to be supplied to the honeycomb structure body 4 is decreased before the lowest temperature in a heating region of the honeycomb structure body 4 reaches the target temperature.
